4 claims. (o1. zie-4,7) The bracket member I 4 may also be called a The invention relatesto a means for mount- ;ing lenses and is particularly adapted to be embodied in eyeglasses, spectacles, or the like.

A particular object ofthe invention is to pro- .5 vide improved means vfor securing the lenses of eyeglasses, etc., to the bows and bridge members.

, 'Eyeglasseswhich embody the invention have a .metallic membersecured in or to the lens.. In y the preferred construction, the metallic members are tubular rivets which fit snugly in holes drilled in the lenses. In other forms Vof the invention,

small metallic discs, etc., .are mounted in apertures provided in the lenses; The bridge members and the bows of the eyeglasses are secured to the metallic membersfby solder, or the equivalent, l the construction being such that the bridge mem- .Abers and thev bows may be assembled with the lenses before the heat is applied to fuse the solder., V C

Other objectsvand advantages will become apparent as the following detailed description progresses, reference being had to theaccompany- :ing drawing wherein f Fig. 1 is a front elevation of a pair of eyeglasses Uwhich embody the invention.

Fig. 3 Ais asection taken on line 3-3 of Fig. 2.

Fig. 4 is a section taken on line 4 4 of Fig. 2.

Fig. 5 is a fragmentary' section taken through eyeglasses which embody another form of the invention.

Fig. 6 is a fragmentary section taken through eyeglasses which embody another form of the invention.

Fig. 7 is a fragmentary section taken through eyeglasses which embody another form of the invention. l

Referring for the present to Figures 1 to 4, inelusive, wherein a preferred embodiment of the invention is illustrated, the reference characters I0 and II designate the lenses of a pair of eyeglasses provided with a bridge member I2, the bows I3 and the brackets I 4, the bows I3 being plvoted to the brackets I4. The brackets I4 and the bridge member I2 are secured to the lenses Il) and II, the bracket members and the bridge member being provided with parts of identical construction to straddle the lenses so that they may be soldered to metallic members secured in the lenses. Therefore it will only be necessary to describe, in detail, the construction of the lefthand (Fig. 1) bracket member I4 and the manner in which it is secured to the lens I0.l This is illustrated in Figures 2, 3 and 4.

.flens mounting member. It` comprises ra bodyv portion i5.. -Secured to the body portion I5 or formed integral therewith is a bifurcated or U- The hole li8 is beveled at its ends.

Resting on the beveledsurfaces i9 are dished members being positioned ktol-face eachother. Ascrewil passes through! an aperture 24 provided in one member 2S and is screw-threaded Obviously, the'screwk 23 secures front and back surfaces of the lens so that a metal to metal contact is 1 made y with the .U -shaped The depressions Il formedin the U-shaped -member I6 areliilledv with solder 25` which solder Ais fused; after the U-'shaped member IB has been assembledv with `the lens IE). The solder rigidly secures the U-shaped member i6 to the metallic ymembers Zt. f

Asbest shown inv Figures 3 and 4, the dished l 'members are each provided with diametrically disposed-lugsZ'I which' engage notches 28 cut in the beveled surfaces i 9. The lugs 2l prevent rotation of the dished members 20 around the longitudinal axis of the screw 23.

As illustrated in Figures 1 and 3, the U-shaped member I6 is provided with laterally extending lugs 29 which engage the edge of the lens IIJ.

In Figure 5 another form of the invention is illustrated. A lens ma is provided with a drilled hole I8a which is beveled at its ends to provide frustro conical surfaces Illa.. Secured to the lens is a bracket member Ida comprising a body portion a to which a U-shaped member Ilia is soldered. It will be noted that the lens I 0a, the bracket member Ilia and the U-shaped member Ia are identical in construction with the lens I0, the bracket member le and the U-shaped member I6, respectively, shown in Figuresl to 4, inclusive. Seated in the beveled endsV o-f the hole I8a are iiat discs 20a which are secured to each other by a screw 23a. The outer surfaces of the discs 20a project a slight distance beyond the front and back surfaces of the lens Illa. The U-shaped member Ilia is secured to the discs 20a by solder The 25a disposed in pockets or depressions lla formed in the U-shaped member 16a.

VFigure 6 illustrates another form of the invention in which the dished members 20 and the discs 20a are replaced with outwardly dished members 20h. The dished members 2Gb are secured by a screw 23h in a hole 18h-drilled in a lens lb. A U-shaped member |61) which is identical in construction with the U--shaped membersl I6 and IGal is secured to the outwardly dished members 20h by solder 25b kdispose-d in depressions or pockets formed in .the

While we have shown and described certain embodiments of our invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made Without departing from the spirit and scope of the invention as disclosed in the appended claims,.in which it is-.our in-k tention to claim all novelty' inherent lnour invention as broadly as possible, in view of the prior art.
